A general guideline is to use about 4-6 quarts of water for every pound of spaghetti. This ensures that the pasta cooks evenly and doesn't stick together.
1lb, the difference in cooked and uncooked weight will be small.
Because it should cook in lots of water.
A spaghetti measurer is used to determine the amount of spaghetti for one serving. Depending on the size of your spaghetti measurer, I have seen up to four servings, you would be able to know how much spaghetti to cook for a certain number of people.
Typically, you should add 1 cup of water to half a cup of rice to cook it perfectly.
Typically, you should add 1/2 cup of water to cook 1/4 cup of rice.
Typically, you should add 1/2 cup of water to 1/4 cup of rice to cook it perfectly.
as much water as rice, so nine cups
The dry noodles themselves should be fine. The water to cook them with, not so much.
A serving size of spaghetti is considered to be 1/4 to 1/2 cup. Since you can not measure spaghetti in a measuring cup let's switch to ounces. 1/4 of a cup of dry spaghetti is 2 ounces, once cooked it measures about 4.5 ounces. So to get enough cooked spaghetti for 1 serving per person, for 20 people you need 20 about 20 ounces of dry spaghetti, or 1.25 lbs. 1.25 lbs of dry spaghetti will cook into approximately 2.8 lbs of cooked spaghetti, which is 45 ounces. 45 ounces which is roughly 5.6 cups, and 5.6 cups divided into 1/4th cup servings of cooked spaghetti gives you about 22 servings. If you feel people are going to want more than 1 serving then cook up another half pound of spaghetti to be safe.
That is approximately 4 pounds dry.
24 oz of spaghetti is a pound and a half.
